Reinforced Bituminous Membranes (RPM)
High performance torch-on bituminous felts provide a robust two or three-layer waterproofing system, suitable for both new build and refurbishment projects. When correctly installed, these systems offer a service life in excess of 35 years, delivering proven long-term reliability.
This form of waterproofing is highly versatile and can be used across a range of roof constructions, including warm, cold and inverted roof systems. Options are also available for incorporating a root-resistant cap sheet, making the system suitable for green roof applications.
High performance torch-on bituminous felts are also a preferred waterproofing option for blue roof installations, due to their strength, durability and ability to accommodate controlled water retention.
Where required, torch-free detailing can be provided in sensitive areas, allowing safe installation in close proximity to combustible construction materials such as perimeters, upstands, roof details and cladding interfaces, without compromising safety or performance.
Reinforced Bituminous Membranes
High-performance reinforced bituminous membrane systems provide a robust and proven waterproofing solution for both new-build and refurbishment projects. T & T Roofing Limited has extensive experience installing torch-on bituminous felts across commercial, residential, and public-sector developments.
Typically installed as two- or three-layer systems, reinforced bituminous membranes deliver excellent durability and resistance to mechanical damage. When correctly specified and installed, these systems offer a service life in excess of 35 years, making them a reliable option where longevity and whole-life performance are key considerations.
Applications & System Flexibility
Reinforced bituminous membranes are highly versatile and suitable for a wide range of roof constructions, including:
- Warm roof systems
- Cold roof systems
- Inverted roof build-ups
Root-resistant cap sheets can be incorporated where required, making these systems suitable for green and biodiverse roof applications. Their inherent strength and robustness also make them a preferred waterproofing solution for blue roof installations, where controlled water retention and long-term performance are critical.
Installation & Safety Considerations
Torch-on systems provide reliable detailing and secure laps, delivering consistent waterproofing performance across complex roof layouts. Where site conditions require, torch-free detailing methods can be utilised in sensitive areas, allowing safe installation adjacent to combustible materials such as perimeters, upstands, façade interfaces, and cladding zones without compromising system integrity.
Our teams are experienced in coordinating these works within live sites and constrained environments, ensuring safety, compliance, and programme requirements are met.
Our Approach
We take a structured and risk-led approach to reinforced bituminous membrane installations, including early review of build-ups, interface coordination, and method selection to suit site constraints. The result is a durable, compliant roofing solution delivered with a focus on quality, safety, and long-term performance.
